Step‑by‑Step Instructions for Overnight Italian Breakfast Casserole
Step 1: Preheat and Prepare the Dish
Begin by preheating your oven to 350°F (175°C). While the oven heats, generously grease a 9×13 casserole dish with olive oil or cooking spray. This step ensures that your Overnight Italian Breakfast Casserole won’t stick, allowing for easy serving later on.
Step 2: Cook the Sausage
In a large skillet over medium heat, add Italian sausage, breaking it into small chunks as it cooks. Stir it well until fully browned, which should take about 8-10 minutes. During the last minute, sprinkle in the Italian seasoning and fresh rosemary, letting the flavors meld together before removing the meat to a plate.
Step 3: Sauté the Vegetables
Using the same skillet, add diced onions and chopped red bell peppers. Sauté these over medium heat for approximately 6 minutes or until softened and fragrant. This not only utilizes the savory drippings from the sausage but also builds a flavorful base for your casserole.
Step 4: Add Spinach and Seasonings
Next, stir in the fresh spinach along with minced garlic, salt, and black pepper. Cook this mixture for an additional 2 minutes, or until the spinach has wilted and releases its vibrant green color. This step is crucial for ensuring the Overnight Italian Breakfast Casserole is both nutritious and tasty.
Step 5: Whisk the Egg Mixture
In a large mixing bowl, whisk together the large eggs, full-fat milk, ricotta cheese, and grated Parmesan. Make sure the mixture is well combined and smooth, as it will serve as the binding agent for your casserole. This creamy blend is what makes the dish so rich and irresistible!
Step 6: Layer the Ingredients
Now, it’s time to assemble your Overnight Italian Breakfast Casserole. Layer half of the cooked sausage and sautéed vegetable mixture evenly in the greased dish. Pour the egg mixture over this layer, followed by the remaining sausage and vegetables. This creates a beautiful, hearty base for your casserole.
Step 7: Refrigerate or Bake
Cover the assembled casserole with plastic wrap and refrigerate overnight for best flavor infusion. However, if you’re ready to bake immediately, place it in the preheated oven and let it bake for 55 minutes, or until the top is set and golden brown. This baking magic transforms your ingredients into a hearty delight!
Step 8: Cool and Serve
Once cooked, remove the casserole from the oven and let it cool for about 10 minutes. This resting period helps it set further, making slicing easier. Now, slice up your delicious Overnight Italian Breakfast Casserole and serve warm for a delectable meal that everyone will enjoy.

Overnight Italian Breakfast Casserole Recipe FAQs
How do I select the best Italian sausage for the casserole?
Absolutely! Look for sausages that have a good balance of fat and spice. A fresh, high-quality Italian sausage will offer robust flavors that enhance the casserole. If you’re watching your saturated fat, opt for turkey or chicken sausage, which still packs a punch but is lighter.
What’s the best way to store leftovers of the casserole?
To keep your Overnight Italian Breakfast Casserole fresh, cover it tightly with plastic wrap or transfer it to an airtight container. It should last in the refrigerator for up to 5 days. I often make a double batch just to have leftovers readily available for those busy mornings when I need a comforting meal on-the-go!
Can I freeze the casserole for later use?
Very! If you want to store the assembled casserole before baking, cover it tightly with plastic wrap and then foil, ensuring no air is getting in. You can freeze it for up to 3 months. When you’re ready to bake, just thaw it in the fridge overnight before popping it in the oven.
What should I do if my casserole looks too dry after baking?
If you find your Overnight Italian Breakfast Casserole comes out a bit dry, it’s often due to overbaking. Make sure you keep an eye on it during the last few minutes of baking and remove it when it’s set and golden brown. If you have leftovers, you can drizzle a little olive oil or a splash of milk while reheating to restore some moisture—trust me, it does wonders!
Are there any dietary considerations I should be aware of?
Yes, indeed! If you’re cooking for someone with dietary restrictions, you can easily adapt this casserole. For gluten-free diets, simply check that your sausage and additional ingredients are gluten-free. If dairy is an issue, substitute ricotta and Parmesan with dairy-free alternatives. Feel free to explore various veggie options to make it fully vegetarian, and you can omit eggs or use an egg substitute to accommodate egg allergies.
How long should I let the casserole cool before serving?
Let your freshly baked Overnight Italian Breakfast Casserole cool for about 10 minutes. This resting period not only helps it set up better for slicing but also ensures it won’t burn your fingers when diving in! Enjoy every delicious bite!
